Bug#969179: iwlwifi: firmware error results in extremely poor connection until reboot
Source: linux
Version: 5.7.17-1
Severity: normal
X-Debbugs-Cc: josh@joshtriplett.org
I get errors like the following regularly, particularly when on video
calls; as soon as the error happens, most or all packets stop going
through, and the connection becomes extremely unreliable.
